Hi *,
please feel free to correct me if I tell sh**: As far as I was told, bad JFFS2 boot performance of u-boot is result of not supporting summary. (Because there is no JFFS2 but only JFFS support?)
It is not missing SUMMARY, it is excessive scanning of empty flash blocks. Look at jffs2/scan.c, it only scan the first 4KB or before declaring the block empty.
